Xinmi Quartet inverter repair

Features four drive: Enclosed electric space design electrical control and main circuit is completely isolated from the environment, enclosed space will drive electrical failure rate dropped to a minimum. Automatic voltage regulator, automatic grid voltage limit can in instability, rapid and stable output voltage, at a current mutation, rapid control of the inverter output current. The drive to achieve long-term trouble-free and reliable operation of drawing machine-specific functions have a volume diameter calculation with feedforward compensation Fast and Accurate PID regulation, disconnection protection, fixed length control other functions, can achieve stable winding operation under all conditions. Intelligent energy-saving operation function This function stressed by load testing, reasonable adjustments inverter output voltage, thereby further improving the efficiency of the inverter. This feature in combination with the traditional method of reducing the frequency of use, achieve higher energy-saving effect of the built-in PID control as standard Enhanced Enhanced PID regulator, independent of the closed-loop parameters set, user-friendly for temperature, pressure and flow, and other closed-loop control. Simplify the control system structure and reduce costs. ? Flexible, diverse analog input, output inverter provides three-way adjustable amplitude analog signal input channels. Users can select current, voltage signal control as required, or to the other device output current and voltage signals. Brake control function 15KW (including 15KW) or less, the standard built-in brake unit, flexible and adjustable brake action ratio. When using a straight flow, brake voltage, braking time, braking current can be set. ? 6-way multi-function terminal can be set, 2-way multi-function OC output, 1 multifunction relay contact output X1-X6, OC1, OC2, TA, TB, TC can be programmed, as many as 30 kinds of output and control options, which greatly facilitates the user's system integration. ? Reliable multiple protection overcurrent, overload, overvoltage, output short circuit protection proximity to 20 weight, in case of failure of the inverter and the motor to implement fast and effective protection. In non-fault conditions, guarantee stability of the system, continuous operation. Cooling fan ON / OFF control of the inverter cooling fan selectable operating state, according to the site ambient temperature can be appropriately set the fan operating status, reducing the power consumption of the drive itself. ? Full range of independent air duct completely independent duct design to ensure good heat dissipation drive. Greatly reduce the possibility of control circuit and the main circuit for environmental reasons damaged. ? Simple, quick parameter copy operation panel, enabling copy and copy all the parameters, the panel itself can be used as removable storage media, it is particularly useful for supporting bulk users. ? Two-line LED display high-brightness dual-line LED display, user-friendly site commissioning. It can simultaneously monitor two sets of parameters (such as PID setting and feedback can be displayed simultaneously), a comprehensive understanding of the motor running. ? Remote keyboard control the underlying hardware interface standard RS485 remote control keypad, annex facilitate the achievement of a stable industrial site remote control, stable communication distance can service more than 1000M. ? Online control standard built RS485 interface, easy to implement other automation equipment interconnection inverter and PLC, IPC, etc., or to achieve more than one drive linkage synchronous operation.
